“AA” size alkaline (only) batteries, into the thermostat’s battery
compartment. Ensure the batteries are installed in the proper direction.
GAS / ELEC CIRCUIT BOARD OPTION (“G” TERMINAL FAN OPERATION): This
setting is a plastic shorting cap called a jumper. This jumper must remain
installed, and set to either GAS or ELECTRIC for your system to work properly.
This setting changes how your system’s blower fan (if applicable) is controlled
while the thermostat is in HEAT or EMERG HEAT mode, when the Fan switch in
the AUTO position. This setting does not affect the fan operation while in COOL
mode.
When set to “GAS”, the blower fan is controlled solely by the heating system
itself. Systems that would typically use the “GAS” setting would be: natural gas,
propane, or oil furnaces, and boilers. NOTE: If your blower fan does not operate
properly after installation, move the Gas / Electric option to the “Electric” setting.
When set to “ELEC”, the
blower fan is controlled
directly by the thermostat.
This setting is required for
heating systems that do not
control their own fan, such as
HEAT PUMPS, and units that
only have an electric-resistive
heating element as the heat
source.
These items below are all located behind the door on the front of the thermostat.
To open the door, pull outwards using the small indentation in the center of the
top edge of the thermostat housing.
HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control
your heating system, and COOL to control your cooling system. The OFF position
will disable both the heating and cooling units.
